Seven Factorial

Currently, the policy of the United States on the Taiwan question is that the US recognizes that polities on both sides of the Taiwan Strait hold that there is only one China and that Taiwan is part of China. In the current tense international climate, it may be useful to considers alternatives to that policy.

Two Chinas Policy: The United States recognizes the independence of Taiwan as a sovereign state, separate from the People's Republic of China.

Three Chinas Policy: The US recognizes Taiwan, Hong Kong, and the mainland as independent states.

Four Chinas Policy: The US recognizes Taiwan, Hong Kong, Macau, and the mainland as independent states.

One China Policy (Retro 1978): The US switches its diplomatic recognition back from the PRC to the ROC.

One China Policy (Retro 1911): The US recognizes the Qing Dynasty as the legitimate government of China and finds some schmuck to play Emperor-in-Exile.

Many Chinas Policy: The US recognizes the sovereign independence of every Chinese province.

Too Many Chinas Policy: Hong Kong makes a perfectly fine city-state, so why not let everyone do that? The US recognizes every Chinese municipality as its own independent state.

1436506450 Chinas Policy: The US recognizes the sovereign independence of every Chinese person.

2^1436506450 Chinas Policy: The US recognizes the sovereign independence of every subset of of the set of all Chinese persons.

2^1436506450-1 Chinas Policy: Same as above, but not including the empty set, because that doesn't even make sense because it's already claimed by Germany.

Infinite Chinas Policy (Countable): The US recognizes that (1) The PRC is a China and (2) for every China c, the successor S(c) is also a China, and (3) for every China c, c != S(c).

Infinite Chinas Policy (Uncountable): The US recognizes that the set C of all Chinas is an ordered field, and that every non-empty subset of C with an upper bound in C has a least upper bound in C.

He does other tessellations, too!

I know I have drawn this shape so often already, but the process of drawing it is so soothing.

And for that, I have drawn a kind of step-by-step guide how to draw that shape in the top of this drawing:

(from left to right: ) [sorry in advance if I make it sound more complicated than it actually is. If you want to draw it, I would advice you to focus more on these illustrations rather than on my gibberish-text.]

1. draw a 2-dimensional Cartesian plane - or, in other words: just draw a cross like depicted

1.1. mark 2 points on the y-axis/vertical line with same distance to the coordinate origin, then mark 2 points on the x-axis/horizontal line with the same distance to the coordinate origin. (The markings on the y-axis need to be farther away from the origin than the markings of the x-axis)

2. connect the 4 marked points like depicted above. This is a function plot of a tractrix. (it has two mirror symmetry axes. )

3. draw an ellipse and connect the two markings on the x-axis. This becomes a kind of "belt" for the pseudosphere (4th picture)

4. part the ellipse into whatever-amount-you-want of partings (like you would cut a cake) and slightly mark these.

5. now imagine you cut that shape horizontally on the outer surface. (In the 5th picture I depicted that with red-ish pen across the pseudosphere. ) -

6. then the cut shape needs to be "(shape) shifted". For that we use a set of marked points we did in step 4). Furtherly, we "cut" the ellipse open, and push one end of it to the top, and the other end to the bottom. (depicted in picture 6 )

7. Then we connect the rest to get that shape:

“I amsick will not to choir because i have a heache. i Hope its very and i am so sorry

love,

blue”

IT WAS ON THE DESKTOP. THIS IS WHAT I SENT.
